What the hell, indeed. But Sam is far more astounded by the sight of Lantar than by anything he might hear him saying.

He shouldn't stare. He knows he shouldn't, because that's rude as hell, but what is even going on here? There's an alien pushing a damn shopping cart full of candy around. Forget amnesia, maybe Sam is actually going a little crazy or hallucinating.

Sorry, Lantar, but there's a dude staring openly at you with his hand frozen in midair as he's reaching for a package of pasta. "Holy shit," he mutters, as if staring isn't rude enough.
